Multi-core chip architectures are becoming mainstream, permitting increasing on-chip parallelism through hardware support for multithreading. Fine-grain synchronization is essential to the effective utilization of the capacity provided by future high-performance multi-core architectures. However, there are also new challenges realizing such fine-grain synchronization in large-scale multi-core c...

Pressure-less consolidation of transparent alumina requires several hours dwelling at high temperature (1600 °C) under a strongly reducing atmosphere (hydrogen). Here, we report on the ultrafast translucent ceramics 1360 °C. Transparency was promoted by synergistic effects initial green density (62.7%) and rapid sintering using Ultra-fast High-temperature Sintering (UHS) technique. The proposed...

We design a multitolerant program for synchronizing the phases of concurrent processes. The tolerances of the program enable processes to (i) compute all phases correctly in the presence of faults that corrupt process state in a detectable manner, and (ii) compute only a minimum possible number of phases incorrectly before resuming correct computation in the presence of faults that corrupt proc...

Abstract Isotropy in microstructure and mechanical properties remains a challenge for laser powder bed fusion (LPBF) processed materials due to the epitaxial growth rapid cooling LPBF. In this study, high-strength TiB 2 /Al-Cu composite with random texture was successfully fabricated by using pre-doped powder. A series of advanced characterisation techniques, including synchrotron X-ray tomogra...

Methods A rate-dependent single crystal plasticity based algorithm is used for the three dimensional analysis of themechanical behaviour of ultra-thin specimens containing flat grains. The specimens are loaded in uniaxial tension. By analyzing the interaction of a single-crystalline matrix with a misoriented grain in the sheet samples, clear insight is obtained in the locally occurring grain–gr...

Grain boundaries are observed and characterized in chemical vapor deposition-grown sheets of hexagonal boron nitride (h-BN) via ultra-high-resolution transmission electron microscopy at elevated temperature. Five- and seven-fold defects are readily observed along the grain boundary. Dynamics of strained regions and grain boundary defects are resolved. The defect structures and the resulting out...
